ENFLOW SEATING OPTIONS All Enflow Trunnion Mounted Ball Valves feature seperate independent spring energized upstream and downstream seal seal rings to ensure absolute seal for both low pressure and high pressure conditions. All Enflow Trunnion Mounted Ball Valves are available in the standard single piston effect arrangement or optional double piston effect or single x double piston effect arrangements. Single Piston Effect The single piston effect is commonly referred to as a safe relieving seat. Line pressure reinforces energized spring force to push both independent upstream and downstream seats against the ball for positive seal. Should cavity pressure trapped between the seats exceed the allowable limits, the excess pressure will push the seat back from the ball and automatically safly release the excess pressure to the lower pressure end of the valve. Released pressure is safely contained within the line. The valve may be installed in either direction. PRESSURE ACTING UPSTREAM AND/OR DOWNSTREAM BODY CAVITY PRESSURE ACTING IN THE BODY CAVITY BODY CAVITY P P P P P P P P UPSTREAM DOWN- STREAM UPSTREAM DOWN- STREAM Double Piston Effect The double piston effect design allows the higher upstream pressure in the body cavity to be utiliized on the downstream side by creating an unbalanced pressure annuls between the outside diameter of the seat inset and body seal diameter. This is accomplished by allowing the body-to-seat holder seal to be forced by pressure against the body providing an increase in pressurized area on the back of the downstream seat holder. With double piston effect seating on both ends of the valve, installation orientation is not a concern. TO AVOID HAZARDOUS PRESSURE BUILD UP IN CAVITY, AN EXTERNAL VENTING RELIEF VALVE IS REQUIRED. PRESSURE ACTING UPSTREAM AND/OR DOWNSTREAM PRESSURE ACTING IN THE BODY CAVITY BODY CAVITY BODY CAVITY P P P P P P P P UPSTREAM DOWN- STREAM UPSTREAM DOWN- STREAM Single x Double Piston Combination The single x double piston effect design combines the benefits of both single and double seat designs. The downstream seat utilizes the higher upstream cavity pressure to reinforce energized spring seal. The single piston seat on the upstream side automatically and safely relieves excessive levels of cavity pressure to the upstream end of valves for containment within the pipeline. This combination allows the cavity relief direction to be controlled. If the valve installation orientation is incorrect, the valve will still function as a single piston effect valve.

KEY FEATURES & BENEFITS GENERAL FEATURES 3 piece bolted body design for ease of field service and maintenance Forged body, bonnet and ball material as a standard, ensures a high integrity material grain structure Body joint integrity is ensured by dual independent seals supported by tight toleranced overlapping metal to metal joint construction capable of withstanding pipeline stress Valves are double block and bleed Valves are antistatic tested Valves are fire safe tested and verified by reputable third party Valves have safe relieving manual bleed valve Valves have drain / flush plug All trunnion valves are equiped with a locking device. For gear operated valves, this feature is included on the gear operator All trunnion valves have ISO 5211 mounting flanges for ease of mounting actuators. Valve compliance with low emission standards Standard document package ISO / EN 10104.3.1 STEM DESIGN FEATURES Valves have anti blow out (blow out proof) stem Stems and trunnions are manufactured separately from the ball and supported by bearing and RPTFE thrust washer to ensure low consistant torques Multiple indendent stem packing seal systems ensures stem seal integrety All valves include emergency secondary stem sealant injection system SEAT DESIGN FEATURES Valves have internal automatic self-relieving cavity (DPE designs are available on request) Special high volume seat insert design facilitate the selection of a broader range of materials while providing an increased life in difficult service conditions Seat ring sealing includes separate graphite seals for maximum assurance in fire conditions. All valves size 6 and larger (smaller sizes on special request where possible) include emergency secondary seat sealant injection system A separate indendent check valve is beneath the seat sealant injection fittings. Our valves are hydrotested utilizing the check valve only Should an injection fitting be damaged, it may be replaced without the requirement of re hydrotesting the valve OPTIONAL FEATURES Double piston effect seats Combination seats (double piston effect on one side and a self-relieving seat on the other) Body may be coated for corrosion protection 6

INDEPENDENT SEATS Independent seats with preloaded springs ensure a bubble tight seal even at low pressures. INTERNAL VALVE STOPS The valve stops are internal, which facilitates easy correct actuation stop setting when the valve is retrofitted in the field. DOUBLE ANTI-STATIC STEM Design includes both the standard stem to ball anti-static device and a unique stem to body anti-static device. BODY JOINT INTEGRITY All body joints have a primary o-ring seal backed by a scondary graphite gasket seal. This is supported by a tight tolerance metal to metal, overlapped, joint construction to ensure fire safe design conformity. 7
